Hafnium tetrachloride: motsoako o phethahetseng oa k'hemistri le ts'ebeliso
Lefapheng la mahlale a morao-rao a k'hemistri le thepa, hafnium tetrachloride (mofuta oa lik'hemik'hale: HfCl₄) ke motsoako o nang le boleng bo boholo ba lipatlisiso le bokhoni ba ts'ebeliso. Ha e na karolo ea bohlokoa feela lipatlisisong tsa mantlha tsa mahlale, empa hape e bapala karolo ea bohlokoa liindastering tse ngata tsa theknoloji e phahameng. Sehlooho sena se tla hlahloba thepa ea lik'hemik'hale ea hafnium tetrachloride le ts'ebeliso ea eona e pharaletseng, e senola boemo ba eona ba bohlokoa ho saense le theknoloji ea morao-rao.
Lintho tsa lik'hemik'hale tsa hafnium tetrachloride
Hafnium tetrachloride ke motsoako oa inorganic o nang le foromo ea lik'hemik'hale ea HfCl₄ le boima ba molek'hule bo ka bang 273.2. Mocheso oa kamore, e bonahala e le kristale e tšoeu e nang le ntlha e phahameng ea ho qhibiliha (hoo e ka bang 193 ° C) le ntlha e belang (hoo e ka bang 382 ° C). Motsoako ona o qhibiliha habonolo metsing 'me o tla potlakela ho hydrolyze ho etsa hydrate e tsamaellanang le eona ha e kopana le metsi. Ka hona, e hloka ho tiisoa ka thata nakong ea polokelo le lipalangoang ho qoba ho kopana le mongobo.
Ho latela pono ea sebopeho sa lik'hemik'hale, molek'hule ea hafnium tetrachloride, athomo ea hafnium e hokahane ka kopanelo ho liathomo tse 'ne tsa chlorine ho theha sebopeho sa tetrahedral. Sebopeho sena se fana ka hafnium tetrachloride thepa e ikhethang ea lik'hemik'hale, e etsa hore e bontše ts'ebetso e ntle mefuteng e fapaneng ea lik'hemik'hale. Mohlala, ke asiti ea Lewis e ka sebetsanang le metheo e fapaneng ea Lewis, e etsang hore e be le boleng ba ts'ebeliso ea bohlokoa ho organic synthesis.
Mokhoa oa ho itokisa oa hafnium tetrachloride
Hafnium tetrachloride hangata e lokisoa ka lipalangoang tsa mouoane oa lik'hemik'hale kapa sublimation. Lipalangoang tsa mouoane oa lik'hemik'hale ke mokhoa o sebelisang karabelo e itseng ea lik'hemik'hale ho arabela metallic hafnium le chlorine mochesong o phahameng ho hlahisa hafnium tetrachloride. Molemo oa mokhoa ona ke hore o ka fumana lihlahisoa tse hloekileng, empa maemo a karabelo a hloka ho laoloa ka thata ho qoba ho hlahisa litšila. Mokhoa oa sublimation o sebelisa litšobotsi tsa sublimation tsa hafnium tetrachloride ho e fetola ka ho toba ho tloha ho tiileng ho ea khase ka mocheso o itseng le khatello, ebe o e bokella ka ho pholile. Mokhoa ona o batla o le bonolo ho o sebetsa, empa o na le litlhoko tse phahameng tsa lisebelisoa.
Tšebeliso e pharaletseng ea hafnium tetrachloride
Sebaka sa semiconductor
Ka tlhahiso ea semiconductor,hafnium tetrachlorideke selelekela sa bohlokoa bakeng sa ho lokisa lisebelisoa tse phahameng tsa dielectric (joalo ka hafnium dioxide). Lisebelisoa tse phahameng tsa dielectric kamehla li bapala karolo ea bohlokoa ho lera la ho kenya liheke tsa li-transistors mme li ka ntlafatsa haholo ts'ebetso ea li-transistors, joalo ka ho fokotsa ho lutla ha hona joale le ho eketsa lebelo la switching. Ho feta moo, hafnium tetrachloride e boetse e sebelisoa haholo lits'ebetsong tsa lik'hemik'hale tsa mouoane (CVD) ho kenya lifilimi tsa tšepe tsa hafnium kapa hafnium compound. Lifilimi tsena li sebelisoa haholo ha ho etsoa lisebelisoa tsa semiconductor, joalo ka ho etsa li-transistors tse sebetsang hantle haholo, memori, jj.
Material Science Field
Hafnium tetrachloride e boetse e na le ts'ebeliso ea bohlokoa ha ho etsoa lisebelisoa tsa ceramic tsa mocheso o phahameng haholo. Lisebelisoa tsa ceramic tsa mocheso o phahameng haholo li na le mocheso o phahameng haholo oa ho hanyetsa, ho hanyetsa ho roala le ho hanyetsa kutu, 'me li sebelisoa haholo libakeng tsa theknoloji e phahameng tse kang sefofane le tšireletso ea naha. Ka mohlala, lebaleng la lifofane, li-ceramics le li-alloys tse entsoeng ka hafnium tetrachloride e le lisebelisoa tse tala li na le melemo ea ho hanyetsa mocheso o bobebe le o phahameng, 'me li ka sebelisoa ho etsa likarolo tsa lifofane. Ho feta moo, hafnium tetrachloride e ka boela ea sebelisoa ho etsa thepa ea ho paka bakeng sa li-LED tse matla a phahameng. Lisebelisoa tsena li na le li-insulation tse ntle le mocheso oa mocheso, o ka ntlafatsang ka katleho tshebetso le bophelo ba li-LED.
Sesebelisoa sa Catalyst
Hafnium tetrachloride ke sesebelisoa se setle haholo se ka sebelisoang mefuteng e fapaneng ea karabelo ea organic synthesis. Mohlala, liketsong tsa organic synthesis joalo ka olefin polymerization, esterification ea alcohols le acids, le acylation reactions, hafnium tetrachloride e ka ntlafatsa haholo ts'ebetso le khetho ea karabelo. Ho phaella moo, tšimong ea lik'hemik'hale tse ntle, hafnium tetrachloride e ka boela ea sebelisoa ho lokisetsa metsoako e kang linoko le lithethefatsi. Thepa ea eona e ikhethang e fana ka menyetla e pharaletseng ea ts'ebeliso mafapheng ana.
Indasteri ea nyutlelie
Indastering ea nyutlelie, hafnium tetrachloride e ka sebelisoa lits'ebetsong tsa pholiso ea li-reactor tsa nyutlelie. Botsitso ba eona bo botle ba mocheso le lik'hemik'hale bo etsa hore e sebetse ka mokhoa o tsitsitseng tlas'a mocheso o phahameng le maemo a khatello e phahameng. Ho feta moo, hafnium tetrachloride e ka boela ea sebelisoa ho etsa lisebelisoa tsa ho roala mafura a nyutlelie ho ntlafatsa ho hanyetsa ho bola le botsitso ba mocheso oa mafura a nyutlelie.
Litebello tsa 'maraka le liphephetso tsa hafnium tetrachloride
Ka nts'etsopele e potlakileng ea liindasteri tsa theknoloji e phahameng joalo ka li-semiconductors, aerospace, le indasteri ea nyutlelie, tlhoko ea 'maraka ea hafnium tetrachloride e ntse e eketseha. Leha ho le joalo, mathata a tekheniki le litlhoko tsa ts'ireletso ea tikoloho ts'ebetsong ea eona ea tlhahiso le tsona li tlisitse mathata a maholo likhoebong. Hajoale, tlhahiso ea lefats'e ea hafnium tetrachloride e tsepamisitsoe haholo-holo linaheng tse 'maloa tse tsoetseng pele,' me matla a tlhahiso ea naha ea heso a batla a le tlaase. E le ho fihlela litlhoko tsa 'maraka oa lehae, naha ea heso e hloka ho eketsa matsete a lipatlisiso le nts'etsopele ea theknoloji ea tlhahiso ea hafnium tetrachloride ho ntlafatsa katleho ea tlhahiso le boleng ba lihlahisoa.
Hafnium tetrachloride, joalo ka motsoako oa bohlokoa oa inorganic, o na le mefuta e mengata ea ts'ebeliso ea k'hemistri, mahlale a thepa, li-semiconductors, indasteri ea nyutlelie le mafapha a mang. Litšobotsi tsa eona tse ikhethang tsa lik'hemik'hale le litšobotsi tse ntle tsa 'mele li e etsa hore e be le karolo e ke keng ea nkeloa sebaka ho mahlale a morao-rao le theknoloji. Ka tsoelopele e tsoelang pele ea mahlale le thekenoloji, sebaka sa ts'ebeliso ea hafnium tetrachloride e tla atolosoa le ho feta, 'me tlhoko ea eona ea mmaraka e tla tsoela pele ho hola. naha ea heso e lokela ho sebelisa monyetla ona, ho eketsa matsete a lipatlisiso le nts'etsopele ea theknoloji ea tlhahiso ea hafnium tetrachloride, ho ntlafatsa bokhoni ba tlhahiso e ikemetseng, le ho fana ka tšehetso e matla bakeng sa nts'etsopele ea indasteri ea theknoloji e phahameng ea naha ea heso.
